This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.
The ChannelSplitterNode() constructor of the Web Audio API creates a new ChannelSplitterNode object instance, representing a node that splits the input into a separate output for each of the source node's audio channels.
new ChannelSplitterNode(context) new ChannelSplitterNode(context, options)
contextA BaseAudioContext representing the audio context you want the node to be associated with.
options OptionalAn object defining the properties you want the ChannelSplitterNode to have:
numberOfOutputs OptionalA number defining the number of outputs the ChannelSplitterNode should have. If not specified, the default value used is 6.
channelCount OptionalAn integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node. (See AudioNode.channelCount for more information.) Its usage and precise definition depend on the value of channelCountMode.
channelCountMode OptionalA string describing the way channels must be matched between the node's inputs and outputs. (See AudioNode.channelCountMode for more information including default values.)
channelInterpretation OptionalA string describing the meaning of the channels. This interpretation will define how audio up-mixing and down-mixing will happen. The possible values are "speakers" or "discrete". (See AudioNode.channelCountMode for more information including default values.)
A new ChannelSplitterNode object instance.
const ac = new AudioContext();
const options = {
numberOfOutputs: 2,
};
const mySplitter = new ChannelSplitterNode(ac, options);
